A Noticble Difference

I saw this on the Engine Masters show, sponsored by Amsoil and tried this in a high performance 502 cu. in. engine that runs on pump gas. Don't know if it really increases the octane number but it makes a notable difference in engine performance. Starts quicker, idles (big cam), runs much smoother, and stopped the dieseling completely. Just getting the engine to idle at 7500 feet altitude is worth the the cost.
Bottom Line
Yes, I would recommend this to a friend.

Boosted?

I have an nguage reading alcohol content and it didn't change any percentage read through the vehicles computer readings. It is possible 1 bottle wasn't enough for the 36 gallon tank on my vehicle. I'll test this theory at a later time.
I have been using AMSOIL products for about 40 years. They have always had superb lubrication products for whatever your application is. Recently I was introduced to the Octane Boost. I have my 2019 Mustang tuned to a bottle added to almost every other tank. Man what a difference. Thanks AMSOIL.
Bottom Line
Yes, I would recommend this to a friend.

Absolutely a must have

I own a high performance snowmobile, so I'm always cautious when i fill up at the pumps as I want 100% premium fuel. Not always the case at gas stations in northern Ontario. Fuel quality seems below the said standard. So I always carry a bottle or two in my tunnel bag to use to bring up the standard that I am always looking for. Cheers
